[R] weird "vector size cannot be NA/NaN" problem

[Werner Wernersen]

Hi,

I have to follow up my own question since this problem is getting quite disturbing and I fear that it also causes other functions to malfunction without notice. 

It occurs quite quite often when I manipulate the mentioned data set. It definitely is caused by the column entries which are Inf (caused by a value/0 operation) but I cannot reproduce the error. When I do a describe(c(5,3,76,4/0)), for example, the last value is Inf but the error is not thrown.

But I can save the vector and load it and the error still occurs. Would someone be willing to look at that vector and maybe finds out the root of the problem? (I'll send the vector by email)

As I said in the earlier email, the data is imported with read.dta of the foreign library and the only manipulation I do is dividing the values of two columns by each other.

Thanks a million,
  Werner
